One endpoint. Every frontier model.

The infrastructure layer between your product and the model providers.

One key, every model
Route to OpenAI, Anthropic, Gemini and more through a single endpoint — switch providers without touching your code.
Usage you can see
Live request, token and latency metrics by provider, so spend never surprises you.
Pay as you go
Top up a balance or subscribe. Transparent per-token pricing with no monthly minimums.
Scoped API keys
Mint, rotate and revoke keys per project. Every key carries its own limits and audit trail.
Secure by default
Credentials stay server-side. Keys are shown once, stored hashed, and rotate in a click.
Drop-in compatible
Speaks the OpenAI API shape. Point your existing SDK at our base URL and you are done.
